What happened
The pilot elected to conduct a training exercise involving a simulated forced landing pattern directed toward a large rice field. During the maneuver, the aircraft was established on the final approach segment. As the aircraft passed over a stand of pine trees located along the approach path, the pilot reported hearing a loud thump sound.
In response to the impact, the pilot increased engine power and aborted the landing attempt. The pilot then turned back toward the home airport. During the en route phase, an inspection revealed a dent on the leading edge of the right wing. This damage was attributed to a collision with a tall pine tree during the initial pass over the trees.
The pilot proceeded to land at the airport without any further difficulty or mechanical issues. The aircraft was recovered safely after the training maneuver.
